JELTE-TRIPP ORG-AN CORPORATION, A CORPORATIONv OF DELAWAREORGAN-SVELL-GONTROL MECHANISM Application filed August 28, 1924, SerialThis invention relates to swell operating mechanisms for organs and itspurpose, generally, is to provide a swell operating means operable undercontrol of a record and which Will beV of generally improvedconstruction by reason of certain novel and advantageous featuresincorporated therein. Among the particular purposes of the invention isthe provision of a swell operating mechanism adapted to open and closeswell shutters in succession and at different speeds, under control of arecord, to provide crescendo or decrescendo effects at varying speeds asWell as sforzando or crash effects.

rlhe foregoing objects, including other of aparticular nature Which Willbe apparent, to those familiar With the class of invention to which thepresent one relates, 'from the drawings and following description andwhich, therefore, need not be set forth in detail, are Well accomplishedby the cons uct-ion illustrated in the accompanying drawing andhereinafter described: it being understood that this particular detailembodiment is merely exemplary and that changes therein may be madeWithout departing from the spirit of the invention defined by theappended claims. y

ln a general Way and as a premise to the description of the particularform of the invention illustrated, l Would say that While the particularembodiment illustrated comprises pneumato-electric mechanism having rsns operable under control of a suitably pr pared, record tosuccessively open and successively close the svvell shutters of theorgan at different speeds, Vto produce the va swell and decrescendoeffects called for by an artistic rendition of a musical compositionbeing played, yet successive operation of the shutters in opening and inclosing is not Wholly essential to the invention, considered in. itsbroadest aspects, While very advantageous and because of its advantagesgreatly preferred: nor is it Wholly essential, though greatly preferred,that the operating mechanism be of a pneumato-electric nature. Again,also by Way of premise, I Would state that in the automatic musicalinstrument art the present No. 734,747. Renewed Auguste, 1930.

practice prefers the use of perforated music rolls or note sheets as therecords therefor, and with such note sheets it is customary to employ asthe tr cker member of the mechanism a bar having perforations Whichcorrespond with the perforations of the ynote sheet but novel featuresembodied in the present mechanism may readily be embodied in a mechanismcontrolled by a record of different nature from that utilizing the Welllrnovvn and preferredv perforated; note sheet, with a correspondingchange in the tracker 'iemben tion is not `primarily concerned With anyparticular style or construction of record or tracker, it should beunderstood that these Words Wherever used in the following-description.and claims unless otherwise qualied,l are not intended to be restrictedto the Well known perforated note sheet andthe Well known bar withperforations or ducts corresponding to those of the note sheet, but onthe contrary are intended to comprehend any suitable form of record andany suitable form of tracker for use with such record. Moreover, inrecord-controlled musical instruments employing pneumaticallyl operablevalves controlled by perforated note sheets, the practice preferspneumatic elements Which operate these valves be subjected to pressureswhich are atV and below that of the atmosphere, but it vis generallyunderstood that other pressure may be employed provided one is higherthan the other. rlherefore, While I have illustrated valve operatingmechanism vof a pneumatic nature wherein the pouches which operate thekvalves are exposed to a pressure below that of the atmospherer at,V

D designates la shutteroperating pneumatic here shown as lhaving its movable wall d con-`nected to the corresponding shutter by a link `rIQ-*and adapted by itsexpansionto close and vhold't'heshutter against vthe action of aret-ractile spring Z), which tends to open Athe shutter; Inpractice,there is, preferably, one

Referringfnowfto the one illustrated, v1() designates a duct whichcommunicates'with the .interior of the pneumatic and isprovided with aportll through which it'may have communication with the interior ofthechest lfCfan'd 'alsowith a port 12 through which it'` may havecommunication with the atmosphere. -When the port 11 is Open andthe'port 12 is closed, the pressure of the air fwithin .the chest 'C Iandvpower pneumatic D, Ybeingfgreaterthan v-that of the atmosphere y view onan enlarged :scalek v of' al portion ofthe structure shown onFigfphere,v and and tension of the spring b, holds the pneumatic inexpanded condition and the shutter closed, and when the port 12 is openand the port 11 is closed there will be, as is apparent, a balancing ofthe pressures of op- 'pneumato-electric means preferably as follows Thestem 14r of the'valve 13 is operatively connectedwith a pouch 15 oneside of Vwhich is exposed to the pressure in the wind chest 'C andtheother side of-which is exposed to the controllable pressure in a chamber16, said chamber having a duct 17- provided with -a-port 18 throughwhich it may be vented to the atmosphere under Vcontrol of a valve 19which -is carried by the armature 2O of an electromagnet 21, "When theport 18 is closed bythe-valve 19, the valve 13 will be seated yupon theport 12 thereby closing the duct `10 against the'atmosphere and openingsaid duct to the pressure chamber C, there being 'ajs'uitable port22,*here shown as arranged between the Ylimbs of the magnet 21 invwhichposition it will beopened when the valve 18 is seated-over the port 19and will -beclosed by said valve when the latter has been moved to openthe port 18 by the energizing of the magnet 21. "This causes the chamber16 to be vented to the atmosphere whereupon the pressure ,in the chestVC `will expand rthe pouchl and move the valve 13 to close the port 11and open the port 12 thereby cutting off communication of the interiorof the pneumatic D with the pressure chamberand opening communication ofthe interior of'said pneumatic with the atmos- V permitting vthe springb to open the shutter. I Y y y ',Each electromagnet is energized anddeenergized to open and close the corresponding vvalve 18 throughsuitable electrical connections, the connections shown comprising wires23 and 24 terminating inlspring con- EQ-formed of copper or othersuitable conductive materialand 'having a diagonal edge e. In theloperation of this member the diagonal edge of the conductive-plateengages the spring contact wires progressively,

beginning :at rthe bottomthereof, Vand closes the-circuits through theseveral electromagnets successively. .Inpractice the lower'contact wireis made lheavier than the other contact wires and isused as a for all ofthe contact wires.

The movable switch member E is connected by links 27 and 28 with themovable walls of the pneumatics F ,and G, in such manner that when thepneumaticV .F is' collapsed said switch member will be operated to closethe circuits to the several electromagnets and cause the shutters to beopened, and when the pneumatic G is collapsed said switch member will beoperated to again open said circuits and cle-energize the magnets,thereby causing the shutters to be closed.

These two pneumatics are operatively reground .wire

Vlated to a valve box H, having, as indicated in Figure 6, a conduitwhich extends to the interior of the pneumatic F and a like conduit 29which extends to the interior of the pneumatic G. The valve box is alsoprovided with connected channels 3l and 32 which extend from the conduit30 to a chamber 33 having an atmospheric port 34 and a suction port 35.A valve preferably the double valve 36 here shown is` mounted in thechamber 33 in such relation to the port that when it is in one of itspositions the atmospheric port 34 will be opened and the suction port 35will be closed and when it is in its other position, said suction portwill be opened and said atmospheric port closed. To bring about thesemovements, its stem 37 is operatively related to a pouch 38, one side ofwhich is exposed to the tension of the air inra suction conduit 39 intowhich the port 35 opens. rlhe other side of the pouch is exposed to thetension of the air in a chamber 40 which tension is variable, thechamber 40 having a duct 4l through which it may be flushed with air atatmospheric pressure under control of a properly prepared record, ashereinafter set forth.v

The conduit 29 is correlated with like channels having atmospheric andsuction ports, respectively, controlled by a like valve and pouch, theseelements not being shown in detail for the reason that they areduplicates of the corresponding elements decribed with relation to theconduit 30. The pouch which is correlated with the conduit 29, and whichcorresponds to the pouch 38,

however, is shown in Figure 6 and is marked 38a and the duct leadingtothe chamber the flushing of which with atmospheric air expands saidpouch 38 is marked 41a.

42 and 43 in Figure 6 designate channels leading from the pneumatics Fand G, respectively. These channels, respectively, open into members, I,and J, which are of like construction, and containpneumatically operablemeans to cause Aeither pneumatic F or G to be vented while the other isbeing collapsed. Each of said members, in the form of the inventionherein shown, has a chamber 44 which is open through a channel 44"L tothe vatmosphere at all times and is provided with a valve 45 operativelyrelated to a pouch 46 mounted in a chamber 47 and having a spring 43which tends to expand it and thereby hold the valve 45 upon its seatover the mouth of the corresponding channel 42 or 43. lt willv beapparent that when the tension of the air in Veither chamber 47 isreduced sulliciently below that of theatmosphere, the pressure of thelatter acting upon the corresponding pouch 46 will move thecorresponding valve 45 from its seat and thereby open the way throughthecorresponding channel 42 or 43 of the corresponding pneumatic with theatmosphere. The operation of the valves 45 to vent the pneumatic Gsimultaneously with the collapsing of the pneumatic F to open theshutters and to vent the pneumatic F simultaneously with the collapsingof the pneumatic G to close the shutters is accomplished as follows Fromthe chamber 33 which is connected to the conduit 39, channels 50 extendand are connected by a duct 5l with the chamber 47 in the member J,(Figure 4) and like channels having a like cross connection (marked 5l?)to the chamber47 ofthe other member I, are provided between the latterchamber 47 and the chamber 33 connected to the conduit 29, the crossconnection being indicated in Figures 4 and 6.

It will be understood, now, that the admis.- sion of air at atmosphericpressure through theduct 41 will cause the pouch 38 to expand and theswitch pneumatic F to collapse, and that this in turnV will operate theswitch member E to close the circuits successively through the magnets2l, causing the several pneumatics D to collapse and the severalshutters B to be opened, and that the operation of the switch member Ewill be unre- -sisted by the pneumatic G for the reason that the latterwill be vented to the atmosphere simultaneously with the opening of theway between the pneumatic F and the suction conduit. Similarly, it willbe understood that the admission of air at atmospheric pressure throughthe duct 41a will cause the pouch 382L to expand and thepneumatic G tocollapse, and that this in turn will open the circuits successivelythrough the magnets 2l, causing the pneumatics D to expand and theshutters `B to close, unresisted by the pneumatic F. The speed at i,

which these operations may be effected may be primarily regulated byproperlyvsetting regulating screws 52, with relation to the air passagesto the chambers 33, respectively,

one of which screws is shownr in Figure 4.

This, however, is an initial regulation which is usually made at thefactory inthe case of small organs or during the installation of largerorgans.

After this initial regulation has been made V erated under control oftherecord to supplement when desired the operations of the beforementioned valves 36'. VThere is one auxiliary valve mechanism for oneset of valves 36 and another auxiliary valve mechanism for the other setof valves 36. As both are identical, a description of one will suflice,

and indeed, I have only' shown one in detaill (Figure 3) although theoperating pouches,

ymarked53 and 54, respectively, are shown 6 and the chiots through whichat- -mospheric air enters to expand these pouches are shown in Figure 2and are marked 62 and 62a in said Figure 3. Upon reference to in FigureFigure 3, it will be noted that a chamber 55,

' the sameV time yms having connection with the conduit 30 through ducts56and 57 initially controlled bya regulating screw 58, is provided witha port 59 through which it may have communication with the suctionconduit. This chamber is also provided with al valve 60 vto open andclosethe port 59 and said valve is in operative relation with the pouch53, one side of which is exposed to the tension of the air in thesuction conduit 39and the other side of which is exposed to the tensionof the airin a chamber 61 having a duct 62 through which it'may beflushed with air at atmospheric pressure undercontrol of the record.Thus, when the duct 62 is opened `to the 'atmosphere, the pouch 53-willbe expanded at the pouch 38 is expanded and the conduit 30 will beplaced in communication with the suction conduit 39 through the port 59as 'well as through ther port 35, thus resulting in a more rapidcollapse of the pneumatic G than takes place whenonly one of said portsis opened. Similarly when the `duct 62a' is opened to the atmosphere,the pouch 54 will be expanded along with the pouch 38a so that the duct29 will be placed in communication with the suction conduit 39 through aport like that marked 59 as well as through a port like that marked 35,this asis apparent resulting in a more rapid collapse of the pneumaticGr than takes place when a port like 35 is opened alone.

Of course,it will be understood thataV gradual crescendo may result fromthe slower collapse of the pneumatic F and a like decrescendo resultfrom the like collapse of the pneumatic Gr, and that a rapidcrescendo,kor sforzando effect, for example, may result from the rapid collapseofsaid pneumatic Fand a like descrescendo or diminu- Y, endo result fromthe rapid collapse ofthe pneumatic Gr, all under control of a suitablyprepared record. u u Y The necessary suction within theappa-racommunication tus isproduced throughua conduit'63 having suitableconnectiony with an approved pump; as will be well understood.

The.v ducts 41, 41a, 62 and 62a are,- of course,'openedunder control ofa properly prepared `member constituting a record, or equivalent, as thelperforated'note sheet L, Jfor example, which travels over a suitabletracker M having special holes 65, 66, 67 and 68. Thesel holes are,respectively, connected, by preference, with primary valve mechanisms,designated N, N, O andO in Figure 2, Vby means of ducts 69, 69a, 70and 7Oa. These valve mechanisms are of identical construction and, therefore,it Will vsuffice 'to illustrate and describe only one of The one-markedN is shown in section in Figure 2, Aupon'rererence to which it'willbeseen that it comprises a Vchamber 71; a port 73 and an atmosphericport74; a double the same in detail.

chamber 72 lhaving a suction valve one of whose members, 75, is arrangedto open and close the suction port and the other of whose members, 76,is arranged to open and close the atmospheric port; and a pouch 77 whichis operatively related to the double valve.

A conduit 78, whichin practice is common to all the valve members, isarranged at the side of the several pouches opposite lthe chambers 71andis connected around the pouches with said chambers by bleed holes 79.The ducts 69, 69a, 70 and 70, connect the tracker vholes 65, 66, 67, and68v with the chambers 71 in the primary'valve mech- Vanisms N, N, O andO, respectively, and

the hereinbefore mentioned Aducts 41 and 41a, connect the chambers 72 ofthe primary'T valve mechanisms N and N with the chamber 40 of the mainswitchfoperatingvalve mechanisms, respectively, Vwhile the hereinbeforementioned ducts '62 and 62a connect the chambers 72 ofthe primary valvemechanisms O and AO'with the chambers 61 of theauxiliary switchoperating valve mechanisms. f u

From the foregoing the operation will-be understood to lbe as follows Toproduce a crescendo effect, the tracker hole 66 is opened' by theregistration'therewith of asuitably arranged aperture .8() in the notesheet. Thisadmitsair `at atmospheric pressure to the duct 41 through theaction of the primary valve mechanism N v40ct the main switch operatingvalve mechanism which controlsA the deflation of the Vswitch operatingpneumatic F andcauses movement of the members of they double valveV 36Vthereof, to the left as viewed in Figure 4,1 closing communicationbetween atmosphere and the chamber 33 and opening betweenthis chamber 33and the suction conduit 39. Communication is thus established betweenthe chamber 33 through the channels 32 and 31 and conduit 30 to thepower pneumatic F (Figures 2 and 6). At the same time, exhaust tensionis also created in the channel 50 which, as previously is crossconnected by a duct 5l to a small chamber (Figure 4) in the member J.Suction being applied in this manner to the chamber 47 of said member dt uch 46 thereof is collapsed and the cer riding valve 45 withdrawn fromits port thereby opening the channel 42 which is in communication withthe opposite power pneumatic designated G and venting said pneumatic tothe atmosphere, so that the latter pneumatic will offer no resistance tothe movement of the switch member E by the collapse of the powerpneumatic F which occurs when its interior is placed in communicationwith the suction conduit 39 by the opening of the suction port 35 andthe clesing of the atmospheric port 34. The copper plate E is thus movedunder the spring wires 23, 24, the body'of the member E sliding in itsguideways `e- (Figure 3). This will cause the diagonal edge c of thecopper plate Ff to engage the spring Contact wires 25 and 26progressively beginning at the bottom thereof. As the contact Wiressuccessively coni-act with the copperplate the lelectro-magnets 21 areenergized and the swell shutters successively opened.

I will now describe the operation when it is desired to produceasforzando effect. At the same time the perforation 82 opens the trackerhole 66, another perforation 83 will open the tracker hole 68. This willresult in a flushing of the chambers 61 and 4() through ducts 41 and 62,respectively, thus causing the iniiation of the pouches 53 and 38. rTheoperation resulting from the inflation of the pouch 38 is the same asthat already described for the crescendo. In addition thereto, by theinflation of the pouch 53 the valve 60 is moved to the left as viewed inFigure 3. This provides an additional connection between the channel 30and the exhaust tension in chamber 39, through the channels 57 and 56,chamberv 55 and port 59, thereby supplementing the first mentionedconnection and causing a much more rapid deflation of the pneumatic Fwith a correspondingly quickened closingI of the circuits through allthe magnets 21 and opening of the several swell shutters.

As soon as the tracker hole 65 or the tracker hole 66 is closed thecorresponding chamber 7l is exhausted through the usual bleed opening79, the air passing into the conduit 78. This permits the collapse ofthe pouch 77, the fall of the valves 74 and 75, with a consequentclosing ofthe chamber 72 to atmosphere andits opening to conduit valve36 vis moved to the right, atmosphere will enter the port 34 and passingby the Way of the chamber 33 into the channel50, the duct 51 and chamber47, thus permitting the spring 48 to press the valve 45 to the left(Figure 4) and close the duct 42. i

t will be understood that by means of perforations in the note sheet ofdifferent lengths, the crescendo effect may be terminated at anypredetermined point between pianissimo and fortissimo if desired.

It will be understood that if a decrescendo effect is desired, thepneumatic G is operated by parts similar to those already described forthe operation `of the pneumatic F for the crescendo. These parts areunder control of perforations registering with the hole 65 of thetracker. In a. manner similar to and by parts similar to the auxiliaryparts for causing a sforzando effect, the pneumatic G has mechanism andconnections which cooperate with the 'decrescendo mechanism to quicklycollapse the pneumatic G, thus quickly closing all of the swellshutters. These auxiliary means are under control of perforations whichregister with the tracker duct 67. l v

In Figure 8, I have shown `a vfragmentalV view of the tracker and notesheet. As the note sheet travels in the direction of the arrow and theperforation 80 uncovers the trackerhole 66, a crescendo effect isproduced by operating the pneumatic F to bring the contactwires slowlyand successively in con.- tact with the copper plate E; When the end ofthe perforation 80 is reached, the movement ofpneumatic F will, ofcourse, stop. When the perforation 81 opeusthe tracker hole 65, adecrescendo is startedby a reverse movement of the pneumatic G and aconsequent successive disconnection of the contact wires from the copperplate E.

As already described the registration of note sheet perforations 82 and83 simultaneously with their respective ducts y68 and 66, causes thepneumatic F to be quickly collapsed with the result that all of theshutters B are quickly opened, giving a sfor- Zando e'ect. In the samemanner, the simultaneous registration of the perforations 84 and 85 withthe tracker holes 65 and 67 will cause the quick `collapse of thepneumatic G and result in the quick closing of all the shutters B.

.At '86, I have shown two tracker holes illulstrative ofthe note holes;the numerals 87',

' 88,v 89y and 90 designating noteVV perforations in the sheet.

Particular'attention is called to thepere' foration 90 whichl I haveillustrated as an example where it might be desired to produce arcrescendo. which is slower .than the normal crescendo, tol be followedby a decrescendo whichis slowerthan the normaldecrescend'o. 1o

In- `ordery to do this, I place a series of adjacent perforations 91'each of which is of suf,-

' ficient length to operate the pneumatic F to cause. some ofv the swellshutters lto open.

" f lSufficient space 92 is allowed between each two perforations, topermit the pneumatic F topause in its operation to be later startedagain in its operation by another perforation. By a manipulation of thelengths of these series of perforations and the spaces therebetween, thedesired effects may be obtained. Vhile actually some of theseoperationsin the swell shutters may cease'beforev Y others are operated, thesequence is so close,

' lingl the shuttersV inthat there will be no variation in the speed ofthe shutters, eX-

Vcept'such variation asis provided for in the record itself, Y InA thisexemplification of the invention the regualting means, such as the speedof collapse as screws 52and 58 are providedto bring about, in af mostefficient manner, the constancy o speed and a predetermination thereof,it being understood that the constancy here referred to, is that whichispresent', except when throughthe record a variation there-V of isbrought about, If desirable, the screws 52' and 58 may be omitted andthe ducts madeaproper size to. give the proper willvbe well understoodby'y those'skilled in the art. It is to be understood, however,l that asuitablek variable regulating means vhas an important advantage in thatcareful sizing of the vducts 1s 'A unnecessary; It will be apparentvthat the screwsl 52 and 58 provide a very simple yetV effective meansoff producing the desired results.
